WRENCH.

Specification of Letters Patent.

Patented Dec. 28, 1909.

Application filed June 17, 1909. Serial No. 502,771.

To all whom it may concern:

Be it known that I, WILLIAM O. STANLEY, a citizen of the United States,residing at Alliance, in the county of Stark and State of Ohio, haveinvented a new and useful Trench, of which the following is aspecification.

This invention relates to that class of wrenches known as chainwrenches, and its object is to provide an adjustable handle in orderthat the wrench may be used in close places, such as trenches, corners,or among other pipes, or in any places where a rigid handle does notpermit of a long pull.

With the herein stated object in view, the invention consists in a novelconstruction and arrangement of parts to be hereinafter described andclaimed, reference being had to the drawings hereto annexed in whichFigure 1 is a plan view. Fig. 2 is a section on the line 2-2 of Fig. 1.Fig. 3 is a section on the line 3-3 of Fig. 2 with the handle shown indotted lines in its various positions.

Referring to the drawings, 5 denotes a wrench head having a jaw faceconsisting of reversely toothed or serrated portions 6 and 7 The wrenchhead carries a chain 8 adapted to be passed around the pipe or otherwork, and cooperating with the jaw faces to grip the same as is usual inthis type of wrench. The chain is adjustably connected at one of itsends to the wrench head in order that it may be lengthened or shortenedand thus adjusted to the diameter of the work To the wrench head ispivoted by a bolt 9 passing therethrough, a handle 10 of suitablelength. The wrench head is in two superposed pieces, spaced apart attheir rear ends to form a slot 11 in which the pivoted end of the handleis received, and said end of the handle has a slot 12 extendinglongitudinally thereof through which the pivot bolt 9 passes, the latteralso serving to hold the two wrench-head sections together.

From a point adjacent to its pivot, the handle is thickened as indicatedat 13 which forms a shoulder 14 on opposite sides of the handle. Thisenlargement is adapted to seat in one of a number of recesses 15 made inopposite walls of the slot 11, and extending to the rear edge 16 of thewrench head at different angles. This edge is semicircular, the centerthereof being the pivot of the handle. The slot 12 is long enough topermit the handle to be pulled lengthwise from the wrench head asufficient distance to slip the enlarged portion 13 out of the recesses15.

One side of the wrench head has a depression 17 having a portion of itswall extending concentric to the aforesaid edge 16. This wall isengageable by a spring catch 18 carried by the handle, whereby thelatter is locked against longitudinal movement. The opposite side of thehead is similarly formed in order that the handle may be inserted eitherside up.

One of the recesses 15 extends in alinement with the longitudinal axisof the wrench head, and the other two recesses are set at an angle ofabout 72 thereto on op posite sides thereof.

The handle is set with respect to the wrench head by disengaging thecatch 18, and pulling said handle outwardly from the wrench head untilthe enlargement 13 is out of the recesses 15. The handle is now free tobe swung around on its pivot, and it is brought into alinement with thedesired recess, and then pushed forwardly to bring the enlargement intosaid recess, whereupon the handle is locked to the wrench head againstswinging on its pivot. The catch 18 also snaps over the edge of thedepression 17 and locks the handle against movement in the direction ofits length. It will be noted that when the handle is in operativeposition, the thrust is borne by the opposite side walls of the recess,and not placed on the pivot 9.

As already stated, the herein described wrench is designed primarily foruse in close places. The handle may be set in the first angularposition, and the work turned as far as possible. Then, with the jawsstill retaining their grip, the catch 18 is raised, and the handle isslipped to the central position and the work then given another partialturn. "With the jaws still holding the work atthe initial point of grip,the handle is now slipped into the second angular position, and anotherpartial turn made. It is therefore possible to give the work threepartial turns without readjusting the jaws. The wrench may be placed onthe work to pull or turn it one way, and also to pull it tle oppositeway without taking the Wrench 0 What is claimed is:

1. In a wrench, a head having a depression on one side, and also beingformed with a slot having recesses extending at different portionmovable into out of the aforeangles, a handle pivotally mounted in theslot, and movable lengthwise with respect to its pivot, said handlehaving an enlarged portion movable into and out of the recess, and acatch carried by the handle and engageable With the edge of theaforesaid depression for locking the handle against the aforesaidlongitudinal movement. 4

2. In a wrench, a head having a series of recesses, a handle pivotallyconnected to the head, and movable lengthwise with respect to its pivot,said handle having an enlarged I said recesses, and means for lockingthe handle against said longitudinal movement, comprising a catchcarried by the handle, and a shoulder on the head engageable thereby. vV

In testimony that I claim the foregoing as my own, I have hereto aflixedmy slgnature in the presence of two Witnesses. VILLIAM O, STANLEY.
